LOOM AN D IN WEAVING PROCESS.

Application filed February 4. 1925, Serial No. 6,834, and in France February 8, 192 1.

The present invention relates to a particular mounting of the warp threads upon a weaving loom for the purpose of producing in the fabric parts of different colours or characters the one following the other in the direction of the warp.

This disposition may proove advantageous for instance in weaving a garment made in one piece wherein the upper and lower parts have difierent colours.

Heretofore, this result could only be obtained in employing at same time different weft threads at the right and the left of the loom, but could never be obtained upon a well defined line, nor chiefly upon a design.

According to the present invention, I use Warp threads which have been folded double, some of them being attached to the cloth beam at the front of the loom and the others being attached to one or two beams at the rear of the loom, everyone of the rear threads entering theloop formed by the respective front thread and then I proceed to the weaving in the usual manner.

The accompanying drawing shows the disposition of the threads upon a weaving 100m.

Fig. 1 is a longitudinal section of the loom.

Fig. 2 shows the disposition of the threads.

Warp yarn threads 1 of a given color are attached to the cloth beam 2 at both ends after having been folded double, and the warp yarn threads 3 of another color are attached to the beams 4t and 5 after passing through the spaces between the threads 1; in this manner the said threads are secured together Without knots.

In the disposition of the Work upon the loom, the operator brings the heddle into the maximum forward position against the loom lathe or lay and brings the latter adjacent the cloth beam 2; he can then readily place the threads 1 through the eyelets in the heddles and in the reed by taking a position in front or at the rear of the loom and by using a hook in order to draw each loop 1 at once through the reed and through the corresponding eyelet; he then engages in the said loops of the yarn which has been suitably brought into line by means of a movable rod either in a straight line or according to a sinuous curve or the like, a second row consisting of the rearwardly situated threads 3 which will be attached to the beams a and 5.

By the use of the two beams for the separate attaching of the odd and the even numbered yarn, I am enabled to facilitate the checking of the work when disposed upon the loom, as well as the rise and descent of the threads and the heddles, and the tension of the said threads, inasmuch as the beams are in the suspended position.

Having thus described my process and apparatus, what I claim as new therein, and my own invention, is:

1. Veaving process for the manufacture of fabrics having different colours or characters in sequence in the direction of the warp upon a weaving loom comprising at the front and at the rear winding means for the warp threads and for the fabric obtained, this process consisting in attaching some warp threads to the front winding means and other warp threads to the rear winding means, everyone of the said warp threads being folded double so as to form a loop, the loop of each of the warp threads attached to the rear winding means being interengaged with the loop of the alined warp thread attached to the front winding means, and in then proceeding to the weaving operation in the usual manner.

2. Weaving process for the manufacture of fabrics having different colours or characters in sequence in the direction of the warp upon a weaving loom comprising at the front and at the roar winding means for the warp threads and for the fabric obtained, this process consisting in attaching some warp threads to the front winding means and other warp threads to the rear winding means, everyone of the said warp threads being folded double so as to form a loop, the loop of each of the warp threads attached to the rear winding means being interengaged with the loop of the alined warp thread attached to the front winding means, the said loops being in alignment upon a line of any desired form while the ends of the threads are attached to the said winding means, and in then proceeding to the winding operation in the usual manner.

In testimony whereof I have hereunto affixed my signature.
